"Error while executing filter StripDomEventAttributesFilter - RangeError: Maximum call stack size exceeded"
Once the error occurs, the only way to fix it is to refresh the page.
The R2 2021 update causes all controls in Classic RenderMode to change their layout and size due to different font-size, font-family and line-height.
Fixing this change is planned for the upcoming Service Pack.
In the meantime, you can use the styles in the attachment. Due to the fact that the selectors are the same as the ones in the built-in skin, you need to load them either in the beginning of the <body> or using RadStylesheetManager. If you are using the StylesheetManager, ensure you set a big OrderIndex for the entry:
<telerik:RadStyleSheetManager runat="server" >
<StyleSheets>
<telerik:StyleSheetReference Path="fixes.css" OrderIndex="99999" />
</StyleSheets>
</telerik:RadStyleSheetManager>Loading the styles in the <head> tag's markup would not work as the Telerik stylesheets are added programmatically at the end of the <head> tag, meaning it will override the preceding files that have the same selector.
The attachment contains a file for each skin and inside it, it has all styles grouped by control. That means you can load only the file for the skin you are using and optionally remove the styles for controls that you are not using. Keep in mind that some more complex controls(e.g. Grid, Editor, DropDownTree, etc.) contain other Telerik controls as child controls, so you would need to keep the styles for the child controls also.
Please excuse us for the inconvenience caused and thank you for your understanding.
Inconsistent behavior between Firefox and Chrome (other browser not tested) when cutting and pasting content within the editor.
We have more advanced cases but I tried to simplify the case here as much as I could.
This has been tested on you demo page at https://demos.telerik.com/aspnet-ajax/editor/examples/overview/defaultcs.aspx
I have tested using Firefox 88 and Chrome 90, both on Widows 10.
Reproduce:
Paste the following content in html-mode:
<p>Lorem ipsum dolor sit amet.</p>
<p>Ut enim ad minim veniam.</p>
<figure>
<img src="../../images/attractions_LosGigantes.png" alt="Test">
<figcaption>Image text</figcaption>
</figure>
<p>Excepteur sint occaecat cupidatat non proident.</p>
Switch to designmode.
Mark text, including the dot after veniam until before the first character in Excepteur
Cut
(First difference noted here)
Goto after Lorum Ipsum
Paste
(Second difference here)
First difference:
In Chrome you get:
<p>Lorem ipsum dolor sit amet.</p>
<p>Ut enim ad minim veniamExcepteur sint occaecat cupidatat non proident.</p>
In Firefox you get:
<p>Lorem ipsum dolor sit amet.</p>
<p>Ut enim ad minim veniam</p>
<p>Excepteur sint occaecat cupidatat non proident.</p>
Second difference:
Chrome:
<p>Lorem ipsum</p>
<p>.</p>
<p><figure><img src="https://demos.telerik.com/aspnet-ajax/editor/images/attractions_LosGigantes.png" alt="Test" /><figcaption>Image text</figcaption>
<div> </div>
</figure> dolor sit amet.</p>
<p>Ut enim ad minim veniamExcepteur sint occaecat cupidatat non proident.</p>
Firefox:
<p>Lorem ipsum.
<figure>
<img src="https://demos.telerik.com/aspnet-ajax/editor/images/attractions_LosGigantes.png" alt="Test" />
<figcaption>Image text</figcaption>
</figure>
dolor sit amet.</p>
<p>Ut enim ad minim veniam</p>
<p>Excepteur sint occaecat cupidatat non proident.</p>
Inconsistent behavior between Firefox and Chrome (other browser not tested) when drag and dropping content within the editor.
We have more advanced cases (when this breaks things like totally like cutting a block with image and caption into pieces in Chrome) but I tried to simplify the case here as much as I could.
This has been tested on you demo page at https://demos.telerik.com/aspnet-ajax/editor/examples/overview/defaultcs.aspx
I have tested using Firefox 88 and Chrome 90, both on Widows 10.
Steps to reproduce:
Switch to html-mode and add the following content:
<p>Lorem ipsum dolor sit amet.</p>
<p>Ut enim ad minim veniam.</p>
<p><img alt="" src="../../images/attractions_LosGigantes.png" /></p>
Switch back to wysiwyg mode
Drag the image and drop it in the middle of one of the text lines. I dropped it just after Lorum ipsum.
Result is very different in Firefox and Chrome
Firefox :
<p>Lorem ipsum </p>
<p><img alt="" src="https://demos.telerik.com/aspnet-ajax/editor/images/attractions_LosGigantes.png" /></p>
<p>dolor sit amet.</p>
<p>Ut enim ad minim veniam.</p>
Chrome:
<p>Lorem ipsum<img alt="" src="https://demos.telerik.com/aspnet-ajax/editor/images/attractions_LosGigantes.png" /> dolor sit amet.</p>
<p>Ut enim ad minim veniam.</p>
We prefer the behavior in Firefox as it works when having mode advanced blocks than just an image. In Chrome the content is split into the new context and broken.

Please, please, please bring the new RadTaskBoard to ASP.NET AJAX!
I was just reviewing the RadTileList and trying to figure out how to do a Kanban board with your controls, and came across what you just released via the RadTaskBoard, and that would be absolutely perfect to have for ASP.NET AJAX.
Thank you!
Progress Telerik seems to be more focused on pursuing technology we’re not using, and There haven’t been major upgrades to the Windows Forms and ASP.NET controls that we use in our legacy apps.
The tools are great and we use them extensively, even in newer upgrades to our legacy apps.
But we haven’t seen a whole lot of improvements where we’d like to see them, so it’s not worth the maintenance cost.
On the Windows Forms side, we spend a lot of time navigating through the multi-layer structures of the tools, a set-wide consistent change that was implemented over 5 years ago. It’s good for consistency, but makes certain properties and events unintuitive. (E.g., “Why won’t this drop down list work handle the ENTER key being pressed?” “Well, that’s actually the enter event in the embedded control.”)
Our biggest usage on Windows Forms tools are RadButton, RadPageView, RadToggleButton, RadTextBox, and RadSpinEditor – and THAT’S IT.
And they are fairly stable and unchanged in the Progress Telerik line.
On the ASP.NET/AJAX side, it’s frustrating not to have things like cascading drop boxes without getting into a whole lot of Javascript and AJAX coding… which sort of defeats the point of buying a product that proposes to do all that for you. That’s been the only thing we hoped to see updated, some kind of way to preload multiple combos and have it auto-filter based on linked selections, and it never happened.
Our biggest usage on ASP.NET/AJAX tools are RadComboBox, RadDatePicker, RadEditor and RadSpell – and THAT’S IT.
These are also fairly stable and have been mostly unchanged in the Progress Telerik line.
Progress Telerik is rightfully focused on more emerging technologies – we don’t fault the company for that – but most of our work is legacy software we built 10-20 years ago and still maintain, or new clients wanting similar products (so it makes financial sense to use the legacy platform as a basis). If we had an unlimited budget and R&D time, we’d LOVE to explore all the newer technologies and platforms… but it’s just not compatible with our business model (which serves small and mid-range companies with VERY tight budgets).
That makes it hard to justify the thousand or multi-hundred dollar maintenance fee to get periodic patches, when the existing versions are stable and working just fine for us.
If seems like Progress Telerik almost treats these tools as legacy products, and that it’s really not focused on them as much. (Again, we understand, that makes sense.)
Greetings!
Description:
I have found a Cross-Site Scripting issue in the rich text editor, RadEditor. This is not in a body where user provides certain strings, rather it's in the text properties which gets sent along with the user input, such as font-style. The developers were able to follow the filtering mechanisms given in at https://docs.telerik.com/devtools/aspnet-ajax/controls/editor/managing-content/prevent-cross-site-scripting-(xss), but it provides protection for the inputs given in <textarea>, and for the properties values. Hence XSS is still possible
Steps for Reproduction:
1. Open up the text editor {{Screenshot 2020-09-23 at 12.08.51 PM.png}}
2. Input a string and change its font style.
3. Click on submit and intercept the request. {{Screenshot 2020-09-23 at 12.14.45 PM.png}}
4. Now we need to modify the request body for parameter of texteditor's ID. You may notice that the font-style is set and sent by using a <span>.
RadEditor1=%253cspan%20style%253d%2522font-family%253a%20%2527MS%20Sans%20Serif%2527%253b%2522%253etextexttext%253c%2Fspan%253e
Change parameter 'RadEditor1's value with the following:
RadEditor1=%253cspan%20onmouseover%253d%2522document.body.innerHTML%253d%2527ioioioioioioioioo%2527%252bdocument.cookie%2522%20style%253d%2522font-family%253a%20%2527MS%20Sans%20Serif%2527%253b%2522%253etextexttext%253c%2Fspan%253e
5. Submit and notice the 200 OK response. Now go to the text editor and notice that the string texttexttext can be seen. {{Screenshot 2020-09-23 at 12.24.18 PM.png}}
6. Put a mouse cursor on the string and notice that it gets changed to ioioioioioioioioo<domainCookies>.

Currently, the asp:Label and telerik:RadLabel are rendering the AssociatedControlID of the ComboBox as for="RadComboBox1" while it should be for="RadComboBox1_Input"
FROM ADMIN:
1) Use Sys.Application.Load event to fix all labels associated with RadComboBoxes:<script type="text/javascript">
function fixLabelFor() {
$telerik.$("label[for]").each(function () {
var lbl = $telerik.$(this)
if ($telerik.$("#" + lbl.attr("for")).hasClass("RadComboBox")) {
lbl.attr("for", lbl.attr("for") + "_Input");
}
})
// Sys.Application.remove_load(fixLabelFor);
}
Sys.Application.add_load(fixLabelFor);
</script>2) Use OnClientLoad of the ComboBox you want to apply the fix to:
<script>
function OnClientLoad(sender, args) {
var ariasettings = JSON.parse(sender._ariaSettings)
if (ariasettings && ariasettings["aria-describedby"]) {
var lbl = $get(ariasettings["aria-describedby"]);
lbl.setAttribute("for", lbl.getAttribute("for") + "_Input")
}
}
</script>
Hello,
I have noticed the changes in your website, demos and documentation, but not all seems to work well on IE 11.
In the new interface of
the left menu dissapear after more clicks (IE11)
However, in ASP.net AJAX demos, the new interface is not looking good on IE 11
For example, https://demos.telerik.com/aspnet-ajax/orgchart/examples/expandcollapse/defaultcs.aspx
The old interface was looking great, I had no problems at all, any control
I hope I will not have the same problems in my ASP.net application...
I suggest update Device Screen Size for
Telerik.Web.Device.Detection
using System;
namespace Telerik.Web.Device.Detection
{
/// <summary>
/// The device screen size based on the its dimensions in CSS pixels
/// </summary>
/// <remarks>
///The default ranges are:
/// Small (to 600) CSS pixels
/// Medium (601-1024) CSS pixels
/// Large (1025 - 1366) CSS pixels
/// ExtraLarge (over 1366) CSS pixels
/// FullHD (over 1920) CSS pixels
/// UHD4K = 5 // 3840
/// UHD8K = 6 // 7680
/// UHD10K = 7 // 10240
/// </remarks>
public enum DeviceScreenSize
{
Small = 0, // 0-600
Medium = 1, // 601-1024
Large = 2, // 1025 - 1366
ExtraLarge = 3 // over 1366
FullHD = 4 // 1920
UHD4K = 5 // 3840
UHD8K = 6 // 7680
UHD10K = 7 // 10240
}
}

I would like to know if Telerik ASPNET Ajax control supports securing CSP by adding nonce- or sha256- as mentioned in https://www.sitepoint.com/improving-web-security-with-the-content-security-policy (Refer section - Protecting Inline Styles and Scripts Using a Nonce).
Hi,
Is it possible to exercise the NullText option for the control RadDatePicker for ASP.NET AJAX
Thanks
Gita
One tool that can help with testing for the contrast ratio is ANDI.
From Admin: Share in this thread the most impactful contrast issue here, sharing the control and its setup, the skin and the exact elements that are failing the contrast test.
Hi Team,
I'm using Telerik.Web.UI Version 2020.2.617
I have integrated it and added a reference in my web application, asked me to upgrade the version of Assemblies "System.Web.Extension.dll" and "System.Core.dll" has to be upgraded to version 4.0, I did that too, Now I'm getting an error while I'm running or doing build "The type or namespace name 'Script' does not exist in the namespace 'System.Web' (are you missing an assembly reference?)", Assembly it is referring to "System.Web.Script.Services", same error is coming for other attributes like "ScriptMethod, ScriptMethodAttribute"
For the Key word "this" it is throwing as below error
It is throwing an error for "System.Linq.Expressions"
Can anyone help me out on this how to resolve these bugs.
Regards
P L P Kumar
